Davinci teeth whitening gels are strong enough to deliver amazing results, but also gentle enough to be comfortable to the patient. Made with the highest quality USA organic, plant and mineral based ingredients, it's a natural choice. The active ingredient in the teeth whitening gel is a food grade Hydrogen Peroxide and contains three key minerals to stabilize and strengthen the enamel. This product whitens as well or better than other dental whiteners, but without the level of sensitivity and side effects that other whiteners can deliver.
